Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed May 10, 1910. Serial No. 560,478.

To all whom it may concern Be it known that I, FRITZ Wivrzmwm, a subject of the Austro-Hungarian Emperor, and residing at Schoneberg, Germany, have invented certain new and useful Improvements in Machines for Automatically Removing the Full Iirns in Spinning and Twisting Frames, of which the following is a specification.

Various processes and devices have already been described for the purpose of automatically exchanging empty cops for full ones.

This invention essentially differs from the hitherto described machines in that on drawing back the spindle the full cops are automatically removed by a fixed stop without interrupting the working of the machine. The machine is provided with a coupling that is connected up when the cop is full, whereby by partial rotation of a shaft and by intermediary of a rod connected therewith the spindles are drawn backward through the amount necessary for removing the finished cop. A special brake device regulates the tension of the thread according to the increasing circumference of the cop.

I shall now describe my invention with reference to the accompanying drawing showing a machine suitable for carrying out the present process, in which Figure 1 is a front view of the machine, Fig. 2 is a back view of the same. Fig. 3 is a similar view with another position of the parts. Fig. 4 is a plan view of the machine. Fig. 5 is an end view of the same. Fig. 6 is a detail showing the method of actuating the shears. Figs. 7 and 8 are detailed views showing a modification of the flier and rotating means between a plurality of spindles.

The textile fibers 17 pass in the manner shown in Fig. 1 to the flier 16. The fibers first pass through a rotary tube 21 of usual construction which is driven by a shaft 18 by intermediary of a groove-pulley 19 and cord 20, and which imparts a certain twist to the fibrous material. The fibrous material passes from the tube 21 to the drawing rollers 22 and then through eyes 23 of the flier 16 to the cop 24.

A shaft 2 journaled in the frame 1 (Fig. 2) and rotated by a belt or other transmission mechanism carries a heart-shaped cam disk 3, which acts on the roller 4. journaled on a rod 5, that on each rotation of the shaft 2, gives the rod 5 a to-and-fro movement. The rod 5 is connected with another rod 6 by a cross rod 8 to form a frame, to which frame is attached a cord 9 passing over pulleys 10, the free end of which cord carries the weight- 11. The weight 11 tends to maintain the rod 5 with its roller 4, constantly against the cam disk 3. A spindle 7 is mounted in said frame and is, consequently, continuously moved to-and-fro therewith, on the free and somewhat pointed end of which spindle the fibrous material or yarn is wound in diagonal windings. In order to accomplish this winding a permanently rotating shaft 12 is provided which is arranged in the frame of the machine and has fitted to it a grooved pulley 13. By means of this pulley and a cord 14, the similar grooved pulley 15, on which is mounted a flier 16, is caused to rotate, carrying the arm of the flier 16 around the pointed end of the spindle 7.

If the spindle be moved to'and-fro in the manner indicated by means of the cam disk 8, while at the same time the flier 16 rotates rapidly around its axis, the fibrous material or yarn will be wound on the spindle along diagonal lines.

A shaft 25, shown in Fig. 1 at the right hand lower end of the machine, is carried in the lower ends of levers 26 and 71 around which shaft the lever 26 is arranged to vibrate. This lever 26 is acted on by a leaf spring 27 fastened to the frame of the machine and which tends to push said lever into the position indicated in dotted lines in Fig. 1. The lower end of the lever 26 is provided with a pawl 28 which engages in a toothed wheel 30 on the shaft 25, meshing with a gear wheel 32 mounted on a shaft 31. The cross arm 8 is provided with an angle arm 29, which on its to-and-fro movement engages with and causes the lever 26 to swing on its axis, and in this manner by the intervention of the pawl 28, the toothed wheel, and, consequently, also the gear wheel 32, and the shaft 31 are intermittently rotated.

The shaft 31 (Fig. 5) is provided with a spiral track 33, with which the free end of a two-arm lever 36 engages. The lever 36 in Fig. 5. The spiral track 33 is so shaped that, on the intermittent movement, the lower end of the two-arm lever 36 is moved toward the right and, consequently, its upper end toward the left, carrying with it the finger 37 and the weight 38 step by step along the rod 39 to the left until they, the arm and weight, finally reach the position shown in dotted lines in Fig. 5. The rod 39 which can turn on its axis 40, presses on the spindle 7 through the medium of a brake block 41, which spindle is rotated by the yarn being wound thereon or by any other well known means, so that as the spinning process progresses a brake action, gradually increasing in proportion to the increasing diameter of the cop is exerted on the spindle. Another two-arm lever 43 is fulcrumed on the arm 35 by means of a pin 42, the lower end of which lever is connected by a link rod with the lever 36, and, consequently, on the displacement or movement of the latter lever, will itself also be displaced or moved on its pin.

The front end of a bar 44 (Figs. 1 and 5) which is normally situated in the position shown in Fig. 1 with a notch 46 behind a fixed catch 47 will, on the swinging movement of the lever 43 just referred to be raised up by this lever and brought into the position shown in dotted lines in Fig. 1. As soon as this has been effected a spring 48 (Fig. 1), the one end of which is fastened to the frame 1, and the opposite end to a rod 49 connected with the bar 44 by a pivot 45, will move this rod to the right,'inasmuch as the notch 46 can no longer prevent this when the bar 44 is raised. The rod 49 is pivoted at its lower end to a fixed part of the frame, and with its upper end contacts with a grooved pulley 50 which is mounted to rotate and slide longitudinally on the shaft 12. If, now the rod 49 be moved in the manner mentioned toward the right then it will carry the grooved pulley 50 with it and a coupling pin 51 projecting laterally from the pulley 50 will be made to engage with a coupling pin'52 mounted'on a shaft 12, so that the pulley 50 will rotate with the shaft 12. A cord 53 fastened to the pulley 50 at one end and connected to a lever 55 at its opposite end will be wound on the pulley 50 when the latter is rotated, and, consequently raise the lever 55 and rock the shaft 54, on which said lever is mounted. A rod 62 (Fig. 2) also mounted on the shaft 54 is held against a block 63 on the rod 6. When the shaft 54 is rocked in the manner described, the rod 62 is carried with it and acting on said block 63 the rod 6 is moved backward in a longitudinal directionto a much greater distance than is normally the case during a to-and-fro movement of the rod when actuated by the cam disk 3. This increased backward movement of the rod 6 carries with it the spindle 7, and the cop 9 wound thereon will encounter a rigid adjustable stop 24 (see Fig. 1) and be halted in its movement, the spindle continuing its travel in a rearward direction will be drawn from said cop, and the latter consequently falls downward onto a. trough or chute A, and is thence directed into a suitable receptacle.

Above the entrance end of the chute A is placed a cutting device 66 which, in the present instance, is in the form of a pair of shears operated in a manner hereinafter described. When the spindle 7 is drawn back in the manner referred to the previously finished cop is, situated above the shears 66, and the blades of the latter must be in an open position so that the cop can fall between them and the yarn be seized by the shears. For this reason. the blades of the shears are normally held in open position as indicated in full lines in Fig. 6. By means of an arm 56 on the shaft 54, a rod 58 connected with the arm 56 by a pivot 57 is moved to the right when the shaft 54 is rocked (Figs. 1 and 6) to bring a projection 59 on the'rod 58, after a certain interval which is so determined that the finished cop in the meantime is moved from the spindle 7 and has fallen between the blades. of the shears, into contact with an arm 60 on a shaft 61, and'turn the latter to cause an arm 60 through the intermediary of links 64 to operate the blades of the shears 66 and cause them to rock on their pivot into closed position, thereby. cutting the yarn or thread connecting the cop to the flier. I

On the extended backward'm'ovement just described of the frame and the spindle 7, a cam or stirrup67 on the rod 6 (Fig. 4) engages with an arm 68 on a shaft 69, thereby roc-king this shaft which actuates the lever 71, serving as. a support for the toothed wheel 30, by swinging it outwardly on its pivot 72 so that the toothed wheel 30 will be disengaged from the gear wheel 32, in the manner shown in Fig. The wheel 32, which previously, as may be remembered, was turned intermittently, being thus. released, the shaft 31, the. spiraltrack 33, and levers 36 and 43 are permitted to return to normal position under the tension of a spring 74, one end of which is fastened to the frame of the machine and the other end to the lever 36, said spring pulling the latter into the position shown in full lines in Fig. 5, so that the weight 38 is again drawn up nearly to the spindles 7 and the brake block ll brakes the spindle with the pressure necessary at the beginning oi the spinning process. The upper end of the two-armed lever 43, by the movement just described, is then disengaged from the bar 44, which latter can then move back into its normal position as shown in full lines in Fig. 1.

Simultaneously with the closing of the shear blades by the rod 58 (Fig. 1) the twoarmed lever 76 connected at its lower end by a link with a pivot pin 57 is turned around the pin 7 5, and the roller 77 on the upper end of this lever engages with and swings the rod 49 on its fulcrum to slide the grooved pulley 50 and its coupling pin 51 to the left, thus uncoupling the pins 51 and 52. The rod 14: is by this same movement of the rod 49, returned to normal position, and again rests with its notch it) be hind the catch 47, so that the bar l4; is held in position indicated in full lines in Fig. 1. As soon as the coupling between the pins 51 and 52 is released, the lever 55, owing to its weight, will fall, and rock the shaft back into its initial position, carrying the rod 62 with it, thus releasing the rod 6 and permitting it to be retracted by the weight 11. until its roller 4; rests against the cam dis: 3. All the parts being thus returned to their initial positions, the working process can be repeated. After the cop has dropped from the spindle 7 and the thread severed, the free end of the thread hanging from the flier 6 is sulliciently long to be engaged by the spindle when the latter is returned to spinning position; and actual practice has demonstrated that the thread will be twisted about the spindle by the retation of the flier without assistance. so that the automatic swinging of a new cop on the spindle will proceed and the spinning proc continue without interruption.

In the modified structure illustrated in Figs. 7 and 8 each spindle is surrounded by a socket a, which rotates loosely in a suitable bearing and merely rotates the spindle 7 by friction. The sockets a are driven from spindle to spindle by means of cords Z), and grooved pulleys 0 in a suitable manner, and at substantially the same speed as the fliers 16 so that the spindles 7, at the beginning of the winding operation are so assisted in their rotation that any breaking of the yarn is prevented. The tension of the yarn with the increasing circumference of the cop is regulated by a suitable brake device similar to that shown in Figs. 1 to 6. Furthermore, a guide plate (Z for the yarn is pivoted on one arm of the flier 16 and is pressed by a spring e against the spindle and also by the weighted outer end of said guide plate, which as the flier rotates exerts a pressure on the spindle due to centrifugal force, consequently this plate continuously presses against the forming and increasing cop. By this means the pull of the thread will be moderate and is only exerted on a short length of the yarn.
